For many people, presbyopia is a challenge that should be dealt with. Actually, presbyopia is the absence of focusing on close things. The reason for this, is the lens within our eyes starts to be less flexible as we get older. The unfavorable part is, many of us will need some sort of corrective lenses, like contacts or eyeglasses and maybe even bifocals at some stage in our lives as this issue worsens.

Not too long ago, people who wore bifocals had very limited choices while they were choosing their corrective contact lenses. Long ago, eyeglasses that had bifocal lenses were the only option available. Today, you could find different styles of bifocal contacts available on the market. They're becoming more popular, as they provide people who wear bifocal eyeglasses with a very appealing alternative to putting on bulky eyeglasses. They're very economical too - making them a more widely used choice in the world of corrective lenses.

A lot of people might not realize the fact that bifocal contact lenses are just like glass lenses in how they work. When using glass lenses, every single lens offers a variety of focus adjustments, one for distance and the other for being close-up on something. Using bifocal contacts, both of the adjustments are included. Right now there are various suppliers that produce several types of bifocal contacts, which means that it might take you a little research to find out which kind is ideal for you.

Some contact lenses however, are created with a special design, called concentric. Just like concentric circles, there are 2 adjustments - one in the centre and the other around the outside. These 2 adjustments in the lens are very unique, with a sharp line between them. Although they might sound difficult to use, many people find that they're simple to use after a little bit of training.

One kind of bifocal lens is the aspheric lens, that have a gradual adjustment of focus. Both powers are in the central area of the pupil, and like the concentric lens, your eye will instantly accommodate these lenses and choose the focus that is ideal to use.

The 3rd and perhaps best lens for bifocal use is the translating lens. Much like bifocal glass lenses, the near correction can be found at the base of the lens, and the distance correction is located at the top. These lenses cannot move when they are inside the eye. This could be perfect for older people, as these contacts will not move around regardless of what you do.

With regards to bifocal contacts, you should ask your eye doctor what he feels is best for your eyes. If you meet the right criteria, odds are you will be prescribed bifocal contacts. If you put on bifocal eyeglasses, you might find these contact lenses to be the ideal option. You could get bifocal lenses in prolonged, everyday or even conventional wear, which is perfect for anyone who wants different choices.
